    摘要： A force limiting gear reducer for a lifting pinion of self-elevating platform, comprising a gear reducer divided in two parts, a first of said parts being directly connected to a pinion shaft and pinion support and a second said part comprising a shaft-mounted prime reducer with brake and motor connected to an input shaft of the first reducer, a reaction arm of the shaft-mounted prime reducer being connected to a fixed point of a jacking mechanism by means of at least one hydraulic cylinder, means to control the oil pressure in the hydraulic cylinder, and abutments limiting the stroke of the hydraulic cylinder.

    摘要： A solar heat collector has a transparent cover and metal fins beneath the cover. Secured to each fin is a tube through which flows water to be heated, the tube having the general cross-sectional configuration of a figure eight and the tube being welded to the fin at one end of the major axis of the figure eight. Round steel bars are disposed on opposite sides of and extend lengthwise to the tube, in the depressions on the sides of tube caused by the figure eight configuration; and a spring clip presses those bars against the tube. As a result, when water in the tube freezes and the tube expands, the bars and spring clip are pressed apart; but when the ice melts, then the spring clip forces the tube back to its original configuration. The structure also provides protection against surges of water pressure.

    摘要： A mobile platform with relatively vertically movable legs, of the off-shore drilling platform type, has a plurality of pairs of opposed racks on each leg, with a row of pinions supported in a pinion carrier for each rack. A link for each pinion carrier is pivoted at one end of the pinion carrier and at the other end to the platform and is disposed in the medial plane of the teeth of the double rack. On the opposite side of the leg from one of these double racks is provided structure for detachably interconnecting the lower end of the leg to the platform for vertical swinging movement of the leg when the leg is in raised position, about an axis parallel to that plane, so that the legs can be swung together at their upper ends when in raised position, into a pyramidal configuration.
